PL-27N26WQ

Alarms, Buzzers, and Sirens

The use of alarms, buzzers, and sirens are common within many areas such as security systems, industrial machinery, and emergency response vehicles. One type of alarm typically used within these industries is the PL-27N26WQ. This alarm is a beeper (alarm) with an operating voltage range of 6V to 15V DC, and the audible sound generated has an output of >=85 dB.The purpose of this alarm is to indicate a situation such as an intruder within a certain area, an emergency alarm, a process time out etc. In this article we will discuss the application fields and working principles of this alarm.

Application Field

The application fields of the PL-27N26WQ alarm are leveraged primarily within the areas of security systems and industrial machinery. This alarm’s ability to generate a loud audible sound alerts those within the vicinity of the alarm when a situation or crisis occurs, in addition to automatically resetting after a period of time. The long life expectancy of this alarm (over 25,000 hours) allows it to provide continuous protection while saving money in maintenance costs.

Working Principle

The working principle behind the PL-27N26WQ alarm is fairly straightforward. It contains a transducer, a transistor, resistors, and condensers. The transducer is responsible for converting energy from circuits into sound waves. The transistor amplifies the signals created by the transducer, which is then emitted through the speaker as a loud sound. The resistors keep the current centered within the circuit while the condensers control the frequency at which the current is emitted.

Advantages

The advantages of the PL-27N26WQ alarm include its long life expectancy of over 25,000 hours, low operating voltage requirement, easy installation, and low power consumption. Its low power requirement allows it to be used in a variety of devices, from small security systems to large industrial machines. It is also reliable, with a low likelihood of mechanical failure after being exposed to multiple vibration cycles.

Installation and Maintenance

Installation of the PL-27N26WQ alarm is relatively simple, as it only requires two additional components: a power source and a switch. Once the power source is connected to the alarm’s terminals and the switch is connected to the ground and the power supply, the alarm is ready for use. Maintenance is also easy, requiring only periodic cleaning to prevent any dust buildup inside the speaker and the circuit board.

Conclusion

The PL-27N26WQ alarm is a reliable and effective device used for a variety of applications, such as security systems and industrial machines. Its long life expectancy and low power requirements make it ideal for installations in multiple locations, while its easy installation and maintenance protocols make it a no-hassle solution for any situation. The alarm’s business application fields are almost limitless and remain as of yet only fully realized with the PL-27N26WQ.
